The SD WILL make a "big" difference in the way the bullets will perform once it gets to the animial, and the 180 grain .338 is a poor choise "If" used on a bigger animial like a moose!!

I think one problem with the origional post is, the .338 Win. mag. shouldn't be in your comparison in the first place, as it's really aimed at bigger game than say, a 270 win. is.

Yes i know, some guys always try to use a bigger bore with "too light" of bullets!!
